How to Improve the Stability of Rental Stage LED Screen?

2018-10-19

Today, with the rapid development of science and technology, LED displays are frequently used in large-scale events such as advertising, performances, parties, and press releases, and the stability of the LED display plays a vital role in the whole process, especially the rental series of LED display in the active site. In order to achieve various display effects, it is necessary to frequently change the display splicing shape, and the requirements for the display screen are not only convenient to install and debug, but also have high stability. So how to improve the stability of the rental stage LED screen? The following is explained from three aspects: material selection, system control plan, and real-time monitoring of the working status of the LED display.

Key materials that determine the stability of the display are LED lights, driver ICs, power supplies, power signal connectors, and excellent structural design. Our requirements for material selection are: internationally renowned brands that carry out relevant tests and various protection functions in response to industry standards. For example, switching power supply selection requirements: there is overheat protection, AC input should support wide voltage, anti-surge. The DC output should have overvoltage and overcurrent protection. The structural design ensures a good heat dissipation method and a fast splicing method while ensuring the appearance and fashion of the cabinet.

Each part of the system control scheme has a hot backup function, including video transmission and receiving equipment, signal transmission cable, etc., which can ensure that the system can automatically diagnose and switch at an extremely fast speed when an unexpected situation occurs in a certain part of the system. When working in the standby device, the entire switching process will not affect the display performance of the site. For example, in order to meet the needs of the stage scene, the display needs to be moved and stitched on the live scene. If a signal input line of the LED display is loosened due to staff negligence or other reasons, in the conventional control scheme, from the occurrence of the loose box to the end of the signal cascade, all the LED displays will be no signal. If a hot backup solution is added to the control system, the hot backup function is activated at the moment when the signal line is loose, and the LED display can still work normally without any impact on the live broadcast site.

The working status of the LED display can be monitored in real time by computer, including temperature, humidity, voltage, smoke, working status of the cooling fan, and so on. Automatic adjustment of various conditions can occur, providing location and alarms for anomalies. For example, when a cabinet has a relatively high internal temperature due to environmental or other factors, the power inside the cabinet may be over-temperature protected if you have not deal with it timely. If the display is monitored in this situation, the system will reduce the internal temperature of the LED display by intelligently adjusting the operating state of the display. When the intelligent adjustment can't lower the temperature to the set target, the system will alarm by the staff setting mode, and provide the abnormal cabinet position to notify the staff to deal with it in time,ensure the normal working state of the LED display.

In short, improving the stability of the LED display should be considered from the aspects of material selection, hardware design, system control project and so on. Need to have an experienced and powerful R & D team.
